Description

Technical Field

[0001] This utility model relates to the field of communication antenna housing technology, specifically to a drop-proof communication antenna housing. Background Technology

[0002] Communication antennas, as key components of wireless communication systems, are widely used in various fields such as the Internet of Things, mobile communication, and remote monitoring. Among them, PCB antennas are widely used in various communication devices due to their advantages such as low cost, ease of mass production, and high integration. In actual use and installation, these devices often face unexpected situations such as drops and collisions. Especially when the devices are installed at heights, the impact force from a drop can easily cause deformation or damage to the device's casing.

[0003] Currently, most common communication antenna housings consist of two plastic shells joined together with screws, with the PCB board directly fixed inside using screw posts or slots. This type of structure has the following significant drawbacks: First, the structural strength of ordinary plastic shells is limited. Under severe impact, the shell is prone to deformation, denting, or cracking. This deformation is directly transmitted to the interior, squeezing or shattering the delicate and fragile PCB antenna, leading to decreased antenna performance or complete failure. Second, the traditional rigid fixing method transmits the enormous impact energy generated during a drop to the PCB antenna with almost no buffering, easily causing internal damage such as solder joint detachment and component cracking. Third, the antenna's connection cable exit points often lack effective protection, making them susceptible to damage from pulling or friction against the sharp edges of the shell during a drop, affecting signal transmission.

[0004] Therefore, the existing communication antenna housings are insufficient in terms of drop resistance, shock resistance, and internal protection. There is an urgent need for a new type of antenna housing to solve the above problems and ensure the safety and reliability of the communication antenna in the event of an accidental drop. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a shockproof communication antenna housing, including a housing, a lug on one side of the housing, two housings spliced ​​together to form an outer housing with a cavity, a PCB antenna disposed inside the housing, a plurality of intersecting transverse and longitudinal protrusions on the inner wall of the housing, the PCB antenna contacting the inner wall of the housing through a buffer, and a connecting wire connected to the PCB antenna extending out of the housing from the lug.

[0007] Furthermore, the buffer includes a plurality of threaded posts disposed on the inner wall of the housing, the ends of the threaded posts are provided with protruding rings, and a gasket serving as a buffer is sleeved on the protruding rings, the gaskets being in contact with the surface of the PCB antenna.

[0008] Furthermore, the housing has a through hole that passes through the threaded post, and bolts are installed in the through holes of the two mating housings to fix the two housings together.

[0009] Furthermore, the buffer also includes a plurality of pillars disposed in the middle of the inner wall of the housing, and a support pad for supporting the middle of the PCB antenna is installed on the pillars.

[0010] Furthermore, each of the lugs has through holes on both sides. After the lugs of the two housings are joined together, they are fixed by a collar fitted on the outside of the lug.

[0011] Furthermore, it also includes a connecting seat, one end of which is snapped onto the outside of the fixed lug, and the lug and the connecting seat are connected by a connector.

[0012] Furthermore, a sleeve located inside the lug is fitted onto the connecting line of the PCB antenna.

[0013] Furthermore, the buffer is made of rubber or silicone.

[0014] This utility model has the following beneficial effects:

[0015] This invention significantly improves the antenna's impact resistance through the synergistic effect of internal reinforcement structure and multi-point elastic buffer. The crisscrossing transverse and longitudinal ridges inside the shell form a stable support frame, effectively resisting the enormous impact force generated during a fall from a height, minimizing shell deformation, and fundamentally avoiding the hard compression of the PCB antenna caused by shell collapse.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 As shown, this utility model is a shockproof communication antenna housing, including a housing 1. The housing 1 is typically made of high-strength engineering plastic (such as PC or ABS) and integrally molded by injection molding. An outwardly extending lug 101 is provided on one side of the housing 1, which is used for the lead-out of the connecting wire and external fixation.

[0026] During assembly, two identical housings 1 are joined together and secured with fasteners (such as bolts) to form a sealed outer housing with a cavity. This outer housing is used to house and protect the core communication component—the PCB antenna 5.

[0027] To significantly enhance the structural strength of the housing 1 and prevent severe deformation upon impact with the ground from a height, a reinforcing structure is provided on the inner wall of the housing 1. Specifically, this reinforcing structure consists of a grid-like or lattice-like support frame formed by multiple transverse ridges 106 and multiple longitudinal ridges 107 intersecting each other. These crisscrossing ridges constitute a strong internal skeleton, effectively dispersing the impact force throughout the housing, preventing stress concentration that could lead to localized indentations, and thus providing a stable survival space for the internal PCB antenna 5.

[0028] The PCB antenna 5 is not directly and rigidly fixed to the inner wall of the housing, but rather contacts it through a buffer component. This elastic contact method ensures that, upon impact, the impact energy is first absorbed and attenuated by the buffer component before being transferred to the PCB antenna 5, greatly reducing the impact force on the PCB antenna 5.

[0029] The connecting wires on PCB antenna 5 need to be connected to external devices. Their routing is designed to extend from the internal channel of the lug 101 formed by the splicing of the two housings 1 into the outer casing. This design makes the connecting wire exit structure robust and less prone to damage from pulling.

[0030] One specific implementation of the buffer is as follows: Multiple threaded posts 103 are arranged around the inner wall of the housing 1. Each threaded post 103 has a larger diameter protruding ring 104 formed at its end. During assembly, a washer 6 made of rubber or silicone is fitted onto the protruding ring 104. When the two housings 1 are closed and tightened, these washer rings 6 are slightly compressed and tightly press against the surrounding surface or edge of the PCB antenna 5, achieving its suspended fixation and buffering. The housing 1 has through holes penetrating the threaded posts 103. Bolts are passed through the through holes on the two mating housings and screwed into the threaded posts 103 to achieve a secure connection between the two housings 1.

[0031] To provide effective support for the central part of the large PCB antenna 5 and prevent it from bending due to its own weight or vibration, multiple pillars 105 are provided in the middle of the inner wall of the housing 1. At the top of each pillar 105 is another buffer component—a support pad 7. The support pad 7 is also made of rubber or silicone, and its height is designed to contact the central part of the PCB antenna 5 and provide stable elastic support. The pad ring 6 and the support pad 7 together constitute a comprehensive buffer system.

[0032] The lugs 101 are fixed as follows: a through hole 102 is provided on each opposite side of each lug 101. When the two shells 1 are joined, their respective lugs 101 also close accordingly, so that the through holes 102 on both sides are aligned to form complete channels. At this time, a collar 4 made of metal or high-strength plastic is placed on the outside of the closed lug 101 on one side, which can quickly fix the two together and is easy to operate.

[0033] Example 1

[0034] Furthermore, a connector 2 can be provided. One end of the connector 2 is designed with a slot, which can be snapped onto the outside of the lug 101 that is already secured by the collar 4. Finally, a connector 3 (such as a screw or pin) is used to pass through the through hole 102 on the connector 2 and the lug 101 to firmly fix the connector 2 to the housing 1. The connector 2 is used to mount the entire antenna housing onto a designated device or bracket.

[0035] To protect the connecting wires extending from the lug 101 from damage due to excessive bending or friction with the sharp edges of the housing, a soft sleeve 8 is fitted over the connecting wires. This sleeve 8 is positioned within the channel formed inside the lug 101, acting as a cable sheath and further enhancing product reliability.

[0036] In this invention, all the buffer components mentioned, including but not limited to the pad ring 6 and the support pad 7, are preferably made of rubber, silicone or other polymer materials with excellent elasticity and damping properties to obtain the best shock absorption and buffering effect.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
